No mysteries here! Former Cold Case actress Kathryn Morris and boyfriend of three years, Johnny Messner, exclusively revealed to Us Weekly that they are expecting not one, but two bundles of joy come September.

"We're beyond excited and doubly blessed!" the happy couple told Us of their twins-to-be. Morris, 44, is best known for her role as Detective Lilly Rush on the now-defunct hit CBS series, which came to an end in 2010.

Indeed, Morris and Messner have another big reason to celebrate: She's currently wrapping up filming for a CBS drama pilot for Surgeon General, and he's just finished shooting for The Outsider with Jason Patric and James Caan.

The pair recently made a stop on Brett Gursky's podcast On The List on the HAHAJK network where they shared how they met on set but did not start their romance until after the show wrapped. "We compliment each other very well," Kathryn shared during her surprise visit. And Johnny quickly agreed, "I worked hard to woo her. We make the best team."

Morris has also had roles in Steven Spielberg's sci-fi epics A.I. Artificial Intelligence and Minority Report, playing Tom Cruise's wife in the latter.
